Most of the style guides advise you to employ block quotation for any direct quote longer than four lines (MLA). But this is generally for essays and such. Does this also apply for fiction, if the character reads a lengthy quote from an actual book (opposed to a fictional one within the fictional story, if that makes sense)? In other words, let's say a character quotes a six line paragraph from Walden; do you have to use the block quotation for that? And please just assume the quote needs to be there. I just want to know what the rule is. Thank you.
